I think the oculus app is launched automatically after I restart windows each time after the tool is installed. Is this normal? In the settings the launching option of the oculus app is not selected.

No that would not be normal unless you have it selected to launch Oculus Home at startup. I have the OTT set to run at start for my game profile settings , but Oculus Home does not launch until I put my headset on.

Hadracadabra how he explains how to create a script for your desktop. Now you can just double click this bat file each time after closing your 'Oculus' app. It will not restart until you double-click the bat file again to allow the service to run. This is much easier than using Task manager and works brilliant.
